Document Type and Number:

Japanese Patent JP2020132659

Kind Code:

A

Abstract:

To provide a reinforcement film excellent in reworkability with lower initial bond strength to an adherend even when an activation treatment has been applied onto a surface of the adherend.SOLUTION: A reinforcement film (10) includes a film base material and an adhesive layer (2) stuck and laminated on one principal surface of the film base material. The adhesive layer includes a photo-curable composition. The photo-curable composition composing the adhesive layer contains a base polymer having a cross-linking structure, a photo-curing agent, and a photoinitiator. The base polymer having a cross-linking structure is formed through a cross-linking reaction of a composition containing a base polymer, a cross-linking agent and a cross-linking accelerator.SELECTED DRAWING: Figure 1
